I was chasing battery drain and was at a loss. I was testing everything, pulling fuses, doing this, doing that. My LTO bank kept going into lower voltages than I felt comfortable with after a few days of just sitting in the driveway. I found a video from the RUclips mechanic Scotty Kilmer. He used a ceramic 1 ohm resistor on the positive of the battery to help find it. So I ordered one from Amazon and gave it a shot. They are dirt cheap. I followed his instructions and immediately I could see a 100mV drain. I was able to trace it to my damn bluetooth led strips. The remote Bluetooth control module never turns off. It was draining my system after 2 days. As soon as I unplugged it the drain disappeared. Now my lithium bank stays at 15.3-14.8 volts for over a week of the car just sitting in the driveway.
I'm glad I have me an Ioxus cap, it really does help with my system 100%. And I've noticed my car starts up real quick, as if it's helping the starter power up. Not sure if it's suppose to do that but not complaining. Keeps the voltage stable and massages the alternator and battery when the bass drops. If ur into SQL, I recommend an ultracap!!
1:17 Woah, 1/10 of an amp? That's way too much. That's 100 milliamps. Most vehicles are less than 5 milliamp (1/200 of an amp), while more modern cars can be up to 15 or 20 milliamps (1/50 of an amp). Anything over 20 milliamps is usually going to be a problem. A 20 milliamp draw should still keep the battery charged enough to crank after a month. A 5 milliamp draw should last for several months. Note that you have to wait for all the vehicles computers to go into sleep mode to measure the true parasitic draw.
Get a multimeter that can read draw. Wire it in line with your positive battery cable and monitor it over time. Make sure you dont open the car door or turn anything on or youll probably pull more than the fuse in the meter can handle.
I know most amps, like regular 1,000 watt or less, will have a tiny parasitic drain. Less than a fraction of 1 millamp. So tiny it's negligible. Really big amps or big capacitors, I don't know what the parasitic drain is. If anyone has examples, let me know. I'm interested.

So my battery will drop from 12.8v to 10.5v within parking and leaving the car in accessory mode for 30 seconds. So I disconnected my power wire running to my amps and now the battery will stay around 12.6 stable with barely any signs of drainage. What would you suppose in this situation?

yupyup, anything with a remote stays on, hardwire them to an ignition wire

Just like an amplifier, the starter pulls a massive amount of amperage when it first engages. So the cap is definitely going to help it.

Another word for it is quiescent current, or the current draw when a thing is powered off but still connected.
edit: for spelling
How do you track down a parasitic drain?
Get a multimeter that can read draw. Wire it in line with your positive battery cable and monitor it over time. Make sure you dont open the car door or turn anything on or youll probably pull more than the fuse in the meter can handle.

Thoughts on 2 walmart platinum agms for 1800 watts? To clarify one under hood other to amps in trunk. I get discount.
only down side is AGM's dont start making power until your voltage drops to about 12v
@@CarAudioEnthusiasts debating on new agm under the hood or bstock loxus in trunk to existing battery. Suggestions?

likely your battery has a weak cell, also what amp are you running, and also how many batteries, what type?

Circuit breaker
sure, but some of us are pulling 600-800amps from the front.
Lol, 101 😆
